Amphibians & Reptiles
The Herpetology Section specialises in amphibians and reptiles from all over the world, but mainly from Europe, Africa, South America, the Middle East and South-East Asia.
Research focuses on taxonomy, diversity, auto-/synoecology, macro-ecology, species conservation, biogeography, species distribution modelling, evolution and phylogenetics.
The constantly growing scientific collection, which currently comprises > 110,000 specimens, is curated by PD Dr Dennis Rödder and Dr Claudia Koch.
Both curators are involved in university teaching and offer seminars, block modules, and excursions for the BSc Biology and OEP MSc degree programmes at the University of Bonn. Final theses (Bachelor/Master) and PhD theses are also supervised.
Innovative methods in morphology, taxonomy, and systematics
Every year, several hundred new amphibian and reptile species are described worldwide. The LIB makes an important contribution to this; since its foundation, type material of more than 700 taxa has been deposited in our section, including over 350 primary types (i.e. holo-, lecto-, and neotypes) and almost 100 syntypes. To identify new species, we use state-of-the-art molecular biology techniques (genetics, genomics, phylogenetics) as well as computer-aided imaging techniques such as µCT-based 3D reconstructions.
Computer-aided analyses in biogeography, evolutionary ecology, and conservation research
We investigate the effects of climate and land-use changes on different time scales, from currently observable distribution shifts and rather short-term distribution dynamics of (invasive) species (several years to decades) to evolutionary adaptations during speciation (several million years). Amphibians and reptiles are particularly suitable for this purpose, as they are highly dependent on environmental factors. Special attention has always been paid to the search for causal ecological mechanisms that determine distribution and abundance patterns in relation to environmental factors. We use the knowledge gained to make forecasts for the future and to become involved in international nature conservation.
